A source later told the Mirror that he publicly declared his verdict of Cowell, reportedly saying: 'I love him. The best... There's nobody like this guy.'

The mogul’s meeting with Lauren’s father comes amid reports that a divorce settlement filed by Lauren’s estranged husband Andrew Silverman warns him to stay away from their seven-year-old son Adam.

Should Cowell break the agreement, Lauren will reportedly be forced to pay her ex a £31,000 fine. New York City businessman Andrew is allegedly so upset that former pal Cowell romanced his wife that he added a string of unusual clauses into his divorce papers.

Lauren has to make sure her son doesn't call Simon - who UsWeekly claimed this week has a ring and will propose to the Manhattanite next year - 'father,' while Andrew has to make sure the child doesn't call anyone but Lauren 'mother.'

TMZ also reports, 'The settlement agreement also provides Andrew cannot trash Simon to Adam and has a legal obligation to make sure no one else around him talks smack.'

Andrew is paying Lauren $3,000 a month in child support. The site speculates that 'Simon will become the cash cow.'

The British TV personality is reportedly worth $370m.
